Aluminium PCB Manufacturer in Shenzhen China Made by Hitech Circuits Co., Limited
What is aluminium PCB board ?
Aluminium PCB board, also named Aluminium based PCB, metal clad (MCPCB) PCB, insulated metal substrate(IMS or IMPCB) PCB, thermally conductive PCBs, etc. Aluminum printed circuit board ( PCB ) is a unique metal-based copper clad laminate with good thermal conductivity, electrical insulation performance and mechanical processing performance. It is composed of copper foil, thermally conductive insulating layer and metal substrate. It is generally including single layer, double layer and multi-layer aluminum pcb board.
Aluminum PCBs are known as printed circuit boards that have a conducting material in them. They are manufactured for the first time in the early 70s. After their development, they become the most popular and demanding universal aluminum PCB of the time. At early stages, they were used in Amplification Hybrid Circuits. But now in the present situation. They are widely used on larger scales. Now it is necessary to have some knowledge about Aluminum PCB, and what role they are playing in our community?
Designing of folding and non-folding printed circuit boards are different from each other. Generally, they are customized to meet the requirement or needs of the customer. They are made on the demand of the customer or client from its base to the printed circuit board. Their thin layer base is made with the well-known base material that is ceramic fiberglass or plastic substrate. Whereas, aluminum PCBs are extremely useful in many different applications. They are excellent thermally conductive PCBs and perfect electrical insulation. It has a highly conducting metal base which delivers great performance.
How Aluminum PCB is made?
Aluminum PCBs are made up of conducting metal base seals, that are covered with the printed circuit layers. Mostly, alloy plates are used, and alloy of silumin, aluminum base, and magnesium are used in their composition. Aluminum PCBs offer an excellent machining performance, high electrical insulation, and high thermal potential. They are slightly different from the printed circuit boards in their structure. But there is a great difference in their performance ratio.
Aluminum PCB made by Thermal Insulation Layers:
Thermal insulation layers are made up of ceramic polymer. These layers play a very important role in modules of aluminum PCBs. The ceramic polymer has viscoelastic properties and great thermal resistance. It also protects the aluminum circuit board from any mechanical and thermal stress.
Base Layer:
In Aluminum PCBs, the base layer is made up of an aluminum alloy substrate. These aluminum PCBs great choice for through-hole technology.
Circuit Layer:
The circuit layer of Aluminum PCBs is made up of thick copper foil. Generally, PCB manufacturers use copper foil in the production of Aluminum PCBs ranging between 1 to 10 ounces. The heat produced by the electronic components is absorbed by the dielectric insulation layer. Whenever current passes from the circuit all the produced heat is transferred to the aluminum layer to get absorbed. All the printed circuits which have improved thermal resistance will increase the lifespan of the electronic product. Experienced manufacturers offer you reliability, superior protection, and heat mitigation.
